Ball Valves are a form of a quarter turn valve that uses a hollow, perforated and pivoting ball (“floating ball”) to control flow. It is open when the ball’s hole is in line with the flow and when the handle is flat in alignment. When the ball is pivoted at 90° by the valve handle and when the handle is perpendicular to it, it is closed. This makes it easy for visual confirmation of the valves status. They are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse.
